Product Features
- TYPE F SELF-TAPPING POINT - cuts machine threads directly into steel crossmembers up to 1/4" thick; drill a pilot hole, drive with an impact, no nut and no pre-tapping
- FLUSH COUNTERSUNK FLAT HEAD - nibs under the head cut a clean countersink in hardwood and softwood decking, so nothing catches a boot, a strap or a skid
- STAR DRIVE, NO CAM-OUT - deep six-lobe recess takes full impact-driver torque without stripping; far more re-drives than any Phillips deck screw survives
- REMOVABLE, SERVICEABLE JOINT - machine threads in the steel survive board replacement; back the screw out, drop a new board, drive the same screw home
- SPECS (1/4"-20 x 1-3/4") - T-30 star drive, 7/32" pilot in steel (Type F chart max: #1 / 0.228"); suits 1-1/4" to 1-1/2" boards over steel frames; steel Type F thread cutting screws, made for trailer deck and floorboard replacement
